Successful Jandy integration with Raspberry Pi and aqualinkd for less than $25

I have been looking for a way for years to integrate my Jandy RS with Vera at a lower cost than the very good but expensive Autelis. Also, the Autelis systems have been out of stock for a long time and so I started searching for alternatives.

I came across the AqualinkD project on Github and with a leftover Raspberry Pi and $7 USB RS485 I have successfully integrated my Jandy system with Vera. Although not all controls are available YET, the developer is actively working on bring new control features. It meets 90% of the daily monitoring and control without having to jump in to iAqualink or the physical panel.

With this this, I can
Control and monitor Pumps
Activate features Features such as spillover or waterfalls.
Monitor and control temperature, and lighting
Monitor SWG system (salt levels, cell heath/diagnostics)

Limitations as of current release
No VSP control . The developer actively working on this.
No one-touch macros. (however, you can effectively recreate this with Pleg/Reactor)

Recommend that you have some experience with Linux/Raspian. This is not a step by step guide and within each of the projects, follow the install/configuration information.

Hardware BoM
1 x RS485 Adapter
1 x Rasberry Pi (Any model will work from the Rpi1 to the Mini-W
1 x Optional USB Wifi Adapter (if using old Pi without Wifi)
1 x SD (or MicroSD) Card for Pi.

Raspian Linux OS on Pi
MQTT Broker such as Mosquitto . This can be installed on the same Pi as Aqualinkd

Vera Plugins
MQTT Plugin
Reactor or PLEG
Switchboard Virtual Switch plugin

High Level Instructions
Use Raspian instructions and AqualinkD Wiki, and Mosquitto MQTT instructions to install and configure Pi and attach to RS485 bus. Make sure you have both serial connectivity and MQTT pub/subscription tests pass. Make sure you configure the aqualinkd.conf file to match your system and test out the built in web interface.

On Vera, install MQTT, SiteSensor, Switchboard, and Reactor (or PLEG) plugins. MQTT needs some additional files from the Github. Some of the SWG telemetry is only available from MQTT and not yet from JSON queries, so both are currently needed if you want to capture as much telemetry as possible and have it presented in Imperihome or the Vera app via native sensors.

Use the API guide on the AqualinkD wiki, use Sitesensor (I use 5second intervals) to monitor switch state and temperature using the following URL:
Some example JSON expressions you can match on:
response.leds.Aux_2 (or more)

If you just want basic SWG info (salt level, generation status you may only need site sensor) . I just insert the values in to a virtual light sensor as it seems to work fine. If you are using Imperihome, the ISS functionality in SiteSensor give you more options to display Generic sensor values.

Configure MQTT to monitor full SWG status. (JSON API gives you basic status) . You can also use MQTT to monitor temps as well if you want. Just create new device for temp and make the MQTT plugin the parent.

Switchboard virtual switches to trigger Reactor/Pleg actions to turn on and off functions. Then use the status of the switch (via sitesensor probe and Reactor/Pleg) to toggle switch if the setting is changed somewhere else and you want the switch to represent the correct current state.

I also personally use a Variable container to give me status of SWG Voltage, Current, Salt Level, Percentage Settings, and fault status. I translate the numerical values from the SWG MQTT updates in to text strings to display on the Imperihome dashboard.


WOW! If I hadn’t already gone with @rstrouse 's plugin and Autelis I would definitely do this. I probably will if I switch to HomeSEER…

Have the additional controls been added yet?

The developer is close to releasing a new version that has a (hopefully) working VSP speed control and OneTouch macro activation. Honestly though, it is rare I really need to use these during the off season so it has not been an issue for me. I just use the iAqualink for those rare times when needed.

The system has worked extremely well for the last 10 months. I think at this point MQTT and JSON have the same controls. However, I have not changed my set up in 6 months since it is working now. I have built a control UI in both Imperihome through Vera, as well as directly via HomeAssistant . Both quite simple to do.
Overall, I still highly recommend this. If anyone is still waiting for Autelis to come back in stock, give this a try first.

New version was recently released (beta) which now adds VSP control. After a year of continuous use, I am now at a point where I rarely touch the native Jandy interface (iaqualink). Other than some RS485 physical layer issues, it has worked well. Since Autelis seems to be basically an abandoned product being OOS for over 2 years, this is an ideal replacement.
